The dual -line virtual host is also known as the smart dual -line virtual host and the smart dual -line website space. The domestic dual -line virtual host refers to the two lines of the same server at the same time. Interconnection and interoperability issues specially launched smart dual -line virtual hosting services.

　　From the perspective of classification, the domestic double -line virtual host includes:

　　Single IP address single network card

　　Dual IP address single network card

　　Dual IP address dual network card

　　There are three types, including single -network card dual IP and dual -network card dual IP. Both have a telecommunications IP address and a Netcom IP address. Telecom users visit the telecommunications IP address, Netcom users access Netcom IP address, so as to achieve rapid access to Telecom Netcom.

　　The biggest advantage of the domestic dual -line virtual hosting: both telecommunications and Unicom line access speed can be faster, and websites visitors or customers who have fundamentally solved or reduce network crowds are fundamentally solved or reduced. loss. There is not much difference between the speed of opening our website in various places, so as to achieve a good user experience.

　　No matter what kind of dual -line, the IP address of the user and the server needs to be parsed to select the line, so it is very important for the IP address analysis technology, equipment and a perfect address library -its principle is that when the user visits the website Check the IP address of this website to the DNS server, and the DNS server will determine whether the user is telecommunications or Netcom access the Internet? It is a telecommunications IP address when telecommunications online; Essence Because this analytical technology has a certain threshold, not every operator can achieve it, but only the domestic double -line virtual hosts that are used with intelligent DNS analysis can be said to be real dual -line services.
